TIN -IPLATE PACKAGE -ilpplication filed June 26,

This invention relates to the packaging of sheets of tin plate and like coated sheet metal 'which is shipped in relatively large sheets, and which on account of its thinness and the 6 character of its coating must have its surfaces, and especiall .its longitudinal edges,- protected against ust, abrasion and other in ury.

'-Heretofore the common practice has been 10 to ship tin plate in wooden boxes, crates .or bales, the bales being formed by placing a rigid slab of some suitable material on the top and bottom of the sheets and binding these together b means of bands encircling the package. v arious objections have been raised to the use of these kinds of packages for shipping purposes. For example, wooden boxes are expensive, comparatively heavy" and fragile, and rarely capable of being used a second time, while the crates and bales heretofore used afl'ord inadequate protection to the edges of the sheets, and do not satisfactorily prevent the ingress of dust and moisture. The object of this invention is to provide a simple and inexpensive shipping package of tin plate, in which the sheets are firmly heldagainst movement u on each other to avoid marring their sur ace's,'and are entirely enveloped in a case which protects them against dust and'moisture and also protects their ed es from damage due to contact with other ob ects. The invention is illustrated in the accompanying drawings in which Figs; 1 and 2 are plan views of sheets of fiber board material cut and creased to form the top and bottom, respectively, of a casing; Figs. 3 and 4 perspective views, respectively, of the bottom with its ed es turned up, and the top with its sides an ends partially folded'down; and

' Fig. 5 a perspective view of a complete package embodying the invention.

In the ractice of the invention a stack of tin plate 1s placed upon a bottom-fiber board sheet which ,is-slightly larger than the t1n plate sheets, its projecting edges being previously cut and creased so that the?! may be readil folded u wardly on the pac A sec- 0nd ber boar sheet considerably larger 1928.

than the plates, which is also previously cut and creased, is placed on the top of the pack and its projecting sides and ends folded downwardly overthe pack to completely en close the package. A corner angle memberis then nested on each of the side corners of the package, and around them binding members in the form of wires, bands, straps, or the like, are tightlyfastened to hold the top and bottom of the case in place and to prevent relative movement of the sheets.

In shipping tin plate, the customary practice is to arrange the packages on the floor of a freight car with their sides lying in planes transversely of the car. Accordingly it is the sides, rather' than the ends, of the packages that are subjected to injury by the jamming together of adjacent packages due to the shocks incident to the abrupt starting and stopping which characterizes freight hauling- To prevent such injury, strips of i wood have heretofore been placed between the sides of adjacent packages, separating them in rows transversely of a car. In the package provided according to the invention, the outer laterally projecting portions of the cover sheet are preferably folded inwardly on the sides of the package to reinforce the sides of the case, thus giving double thicknesses' of fiber board at thesides, and making it unnecessary to separate the adjacent sides of packages by strips of wood.

Having reference to the embodiment of the invention illustrated in. the accompanying drawings, a fiber boardcasing'consisting of a rectangular top 1 and a rectangular bottom 2 is shown, the edges of which are creased and cut as shown by'the dotted and full lines 7 in Figs. 1 and 2, whereby they may be readily formed to shape. The fiber board'employed in making these casings may be plain cardboard, corrugated cardboard, or other like materials, all of which are herein designated as cardboard. To give it the necessarybody,

it is preferably from one-sixteenth to onequarter of an inch in "thickness depending in part upon the strength of the particular materialused. The bottom sheet is made slightly larger thanthe tin plate sheets to be protected, and its edges are folded upwardly to form a box-like container such as illus-' trated in Fig. 3. The'top sheet used for covering the top, sides and ends of the package is preferabl made from a piece of fiber board consi era-bly larger than the tin plate, and is also creased and cut as indicated in Fig. 1"to form the sides 8and-ends 9 which are folded downover the stack in the manner shown in Fig. 4 to form a dust-proof package.

The outer laterally projecting end portions 3 and 4 of cover 1 are folded inwardly along the sides of the package, reinforcing the sides of the casing to protect the side edges of the tin plate from damage due to shock received in shipping. When the casing is folded in place, an le irons 5 are nested on the side corners o the package, and around them suit- .able metal strands or bands 6 are tightly drawn, holding the casing firmly inplace and preventing the sheets in the package from moving relative to one another. The angle irons project beyond the planes of the casing and prevent the encircling bands from contacting with and injuring the edges of the tin plate. k It will be noted that no glue or connecting means, other than the binding bands are used for holding the casin members in their folded positions orv in place, and that the casing is formed on the package with comparative ease. Thusthe labor incident to thepacking of the sheets for shipment. is

. very small, a comparatively inexpensive package being formed of light weight material which affords adequate protection to the enclosed sheets of tin late. Other advantageous features of pac ages embodying the invention are that-the angles employed in the packages may be used repeatedly, the fiber board may be readily salvaged, and, as stated, strips of wood need not be used for ,separating'the sides of packages in freight cars.

According to the provisions of the patent statutes, I have explained the principle and operation of my invention, and have illus: trated what I now consider to represent its best embodiment. However, I desire to have it understood that, within the scope of the appended claims, the invention may be prac ticed by other forms than those specifically shown and described.

Iclaim: 1'. A sh pping package of tin plate, comprising rectangular top and bottom covering sheets of thick fiber board, said bottom sheet 7 being slightly larger than the tin plate and having its projectingsides and ends folded upwardly against the lower portions of the sides and ends of the tin plate, said top sheet being materially larger than the tin late and package, and metal strands boundaround the top, bottom a-nd'sides of the package and upon said angles.

2. A shipping package of tin plate, comprising rectangular top and bottom covering sheets of thick fiber board, said bottom sheet being-slightly larger than the tin plate and velop the ends of the tin plate and their outer portions being turned laterally against and reinforcing said'downwardly turned sides, a metal angle nested upon the fiber board at each side corner of the package, and metal strands bound around the top, bottom and sides of the package and upon said angles.

3. A shipping package of tin plate, com- I prising top and bottom covering sheets of thick fiber board larger than the tin plate and having protecting sides and ends' folded against and completely enveloping the sides and ends of the tin plate, an angle member nested upon the fiber board at each side corner of the package, and metal strands bound around the top, bottom and sides of the package and u on said angles, said cover sheets being so ormed and foldedthat they are firmly held in their folded positions by said angles and metal binding strands.

In testimony whereof, I sign my name.
